No, it doesn't have nearly the capabilities of a real mailing list system.

Mailchimp is out because it was bought for so much money that the money squeeze is going to be intense.

Mailman is robust once deployed and the initial build-out is not too painful.

FWIW, sendmail is now working on Diffie, running Deb 10 and Postfix (no Mailman installed). I suspect there is a grace period after re-install during which Sendmail / port 25 is blocked. It may flip at midnight, based on one email I saw come through after having been queued for a while.

I also created a second instance at Interserver yesterday, though it is running Deb 9 and does not have an SPF record - or even a name (presumably it will be "hellman", obviously). I will flip it to Deb 10 and add it to the Deadmandao.com SPF record.

Create Instance

Interserver Web Interface

  1. go to interserver
  2. create an instance
    1. Single Slice ($6/mo at this time)
    2. Debian 9 (Deb 9 has Mailman 2, Deb 10 has Mailman 3)
    3. KVM
  3. set reverse DNS to diffie.deadmandao.com
  4. Note the IP address

Update to Latest

Log in root@ip.address using password you provided 

apt-get update

apt-get -y install sudo
adduser bob
usermod -G sudo bob
exit

Host MX Settings

Log in to bob@ip.address

Set SPF

sudo apt-get install net-tools
sudo ifconfig

That'll give you the ip4 and ip6 addresses, which go into the DNS text record:

  • v=spf1 ip4:66.23.226.216 ip6:fe80::216:3eff:fe24:10e1 -all

Set Other DNS

  • A Record, diffie, 66.23.226.216
  • A Record, @, 66.23.226.216
  • CNAME Record, www, diffie.deadmandao.com
  • CNAME Record, mail, diffie.deadmandao.com
  • TXT Record, diffe, v=spf1 ip4:66.23.226.216 ip6:fe80::216:3eff:fe24:10e1 -all
  • MX Record, deadmandao.com, mail.deadmandao.com, 10

Set Hostname

sudo apt-get install emacs-nox
sudo emacs -nw /etc/hostname
> diffie
sudo emacs -nw /etc/hosts
> 66.23.226.216	diffie.deadmandao.com diffie
sudo reboot

Log in to bob@diffie.deadmandao.com 

hostname
hostname --all-fqdn
dnsdomainname

Postfix

SMTP Server

sudo apt-get install postfix
  • Internet Site
  • deadmandao.com is the host domain
  • send a test email
echo "Subject: sendmail test" | /usr/sbin/sendmail -v emailaddress

Had trouble with IPv6 in Debian 9 ("Network is unreachable"). Used the following in main.cf to switch to IPv4 only. 

# inet_protocols = all
inet_protocols = ipv4
